Winter is a time for the industry to settle down a little, reflect on the previous year, and make plans for the coming year on how to improve performance. The water situation to date has not improved significantly so far this winter, while there has been good rainfall recorded within the catchment areas, runoff or stream flow has been low to date. On the back of a severely restricted stream flow last year, this remains a concern for the Department of Water and our supplier the Water Corporation. Innovation in the water industry has been a key topic within the industry to become more efficient and to future proof our water resources in Western Australia. We were recently invited to attend an innovation day with the Department of Water to assist in identifying new ideas on water savings. While preparing for the day, I spent some time reflecting on what we could do as an industry to be more innovative, below are some thoughts on how the industry can work better in this area. 1. Identify and use fit for purpose water sources for use in irrigation 2. Understand and promote new technology for efficiency in irrigation i.e. ET watering systems 3. Educate our customers and contractors on new more efficient products for use in irrigation applications 4. Continue best practice efficient irrigation design and installation It seems as though we may be in for another year of tight water resources. It is up to everyone in the industry to continue to strive to do our best to be as efficient New Water for Food website as we possibly can. I hope you enjoy this issue of the Overflow.

4 Marangaroo Golf Course Irrigation Upgrade By Grant Chettleburgh and Chris Langsford Veiw from the first tee Marangaroo Golf Course is one of two 18 hole public golf course facilities within the City of Wanneroo. Designed by Murray Dawson and opened in 1998, Marangaroo Golf Course is located on 60 hectares of Crown Land in the suburb of Marangaroo. The course measures 5,616 metres (6,177 yards) off of the back tees and averages 95,000 rounds of golf per year, catering for public and social group players. In August 2015, the City engaged Davey Shearer Golf Design to develop Masterplans for both Marangaroo and Carramar Golf Courses to capture potential future development in relation to: Key Course layout improvement recommendations addressing design rationale, hole description and an overall plan for each course; Key operational improvement recommendations addressing general maintenance, turf, irrigation and water management, signage and environmental management. To enable the City to prioritise future capital works and budget accordingly. The existing irrigation system was a mix of Rainbird, Hunter and Toro sprinkler heads. The control system consisted of up to fifteen individual controllers; these were either Hunter ACC or Rainman controllers located around the course acting as a satellite system. There was no central control, so the system had to be balanced accurately to achieve the correct pressures at the sprinkler heads. This made daily program changes very difficult and time consuming. Simple tasks such as turning the system off during rain events required visiting each of the fifteen controllers and manually switching them off. Accurate precipitation rates were non-existent, which made managing golf course greens during a Perth summer very difficult. Due to the aging mainline and constant failures, the system was not able to be pressurised. This meant the system relied on an aging pump start cable, which eventually failed. In the interim prior to the installation of the new system, remote pump starts were installed to half of the irrigation cabinets around the course to keep the course irrigated. The City s Ground Water Licence (GWL) for the course allows for 223, 860KL per annum of ground water to be applied to the approximately thirty hectares of irrigated turf at Marangaroo. This equates to just under 7500KL/Ha per annum which is the standard for active sports fields in Perth, but is considered to be low for ground water allocations for golf courses in the Perth Region. As part of the City s annual capital replacement program, the irrigation at Marangaroo is currently being upgraded over the 2015/16 and 2016/17 financial years. The works are funded through the profit from the two golf courses where 27% of the profit is used to fund future capital projects. These works are part of an overall Masterplan for the golf course to ensure that the City can reduce ground water use and provide a quality turf surface for the next twenty years. A tender was advertised for the works in March 2016, with the contract awarded to LD Total on May 25, With works scheduled to begin on June 26, 2016 and to be completed by the 31 of August 2016, the schedule is incredibly tight. The project is currently on schedule with seven holes installed. The main objectives for the new irrigation system were: Design to be based on the proposed new Masterplan layout Design to allow for hydro zoning of out of play areas on the golf course On completion, the new system will allow for the efficient application and management of water to the golf course for the next thirty years and beyond. Hard edge irrigation design to eliminate water loss in non-turf areas Installation of a central control system with two wire communication Valve in head decoder sprinkler installation to fairways and greens Installation of a weather station to allow for watering based on ET for the different grass types Installation of a dosing system to allow for the direct injection of wetting agents and associated turf products through the irrigation system Installation of polyethylene mainlines, sub-mains and laterals to extend the life of the system Trenchless pipe installation through the poly ploughing method was specified in the tender to minimise disturbance to the golfing public during and after the installation. This means there is no turfing on fairways, tees and green surrounds except for where sprinklers have been installed. To date in the installation, the only issues have been with the plough hitting old tree stumps and logs that had been buried around the course. In these instances, the stumps and logs have been excavated to allow for the pipe to be installed to the specified depth. The trade off with having poly mainlines is that if there is a mainline break then the repair time is much greater than that of a conventional PVC mainline. To counteract this, all joins in the poly lines have been completed by utilising electro fusion welding and each hole has been designed so that each fairway can be isolated in case of a mains break, while still ensuring that every green on the course has a supply of water to it. Each fairway is able to be isolated independently of each other to ensure there will always be supply of water to at least 17 fairways and all greens on the course. If there was to be a mainline break around a green, then they are sized so that a coupling can be used until a weld can be organised. Six separate two wire paths have also been installed to help minimise the effect of any two wire failures. Through close consultation with the designer and installation contractor, the City s Project Manager - Chris Langsford is ensuring that the system is being installed as per the design. After each hole has been surveyed to the as-approved plans, representatives from the City of Wanneroo and LD Totals Certified Golf Designer meet onsite to make changes where appropriate to ensure the hard edge desired on the tree line of the rough is achieved. After these changes are made they are checked by LD Totals Certified Golf Designer to ensure the desire Distribution Uniformity of 85% is still being achieved. Works do not start on a hole until final approval has been given by the City of Wanneroo and LD Totals Certified Golf Designer. A Toro Lynx Central Control System was selected with Toro Infinity valve in head sprinklers to be installed on all fairways, tees and greens. The unique flow management capability of the system uses the design and technologies put into the Toro sprinklers. Each Toro Lynx System offers two 27 monitors at the central control system, one being an interactive map with all layered Autocad drawings and the other showing a simple and easy to navigate programing screen. Lynx, in conjunction with the decoder interface has direct contact with each decoder for simple and easy to navigate diagnostic screens when maintenance is required. This delivers superior diagnostics, directly to each valve in head sprinkler. The Lynx system is supported during extended business hours by Toro s National Support Network (Toro NSN). With NSN, customers have a dedicated and accessible resource for central control system troubleshooting, problem solving, system operational assistance and extended warranty on their Toro computer and central components. If needed, NSN s 24- hour emergency support service is there to help minimise disruption to the operation of the irrigation system. Toro manufactures two different models of sprinklers with decoder in head. One which has the decoder attached to the side of the sprinkler, lying underneath the flange, and the other, an Infinity sprinkler, where the decoder, pilot valve and wire connection are housed inside the sprinkler head. The Infinity sprinkler was selected for the install because all components are easy to access through the top of the sprinkler head. This was seen as a huge benefit due to the fact that all components of the sprinkler are accessible through the internal body of the sprinkler, meaning that the surrounding turf surface does need to disturbed for maintenance of the decoder, solenoid coil and pilot valve. The decoder, solenoid coil and pilot valve can all be physically taken out of the sprinkler simply by releasing one screw, and the irrigation line does not need to be isolated. As part of the contract, a nine week Rotors being adjusted Finished joint installation window was stipulated with a commencement date of 26 June The nine week installation window was critical to minimise disruption to players and minimise financial loss to the City and golf course operator from the course being closed. Prior to commencement of the works, an extensive consultation period was held with the key stakeholders involved in the management of the golf course, including the course operator and maintenance contractor. Golf Course patrons were also kept informed of the pending works and potential disruption to play through signage at the course. The Project Manager, golf course pro-shop, course maintenance team and LD Total have worked closely together to ensure that the golfing pubic are always safe and that by the close of business Friday all eighteen holes are open for play and open to the golfing public. On completion, the new system will allow for the efficient application and management of water to the golf course for the next thirty years and beyond. The design of the system takes into account the masterplan for the golf course meaning that mainlines will not need to be relocated to accommodate any future works. 6 The Overflow - Winter 2016 The Overflow - Winter

5 John Simons Lucerne: DAFWA research officer, John Simons checks out the lucerne trial at Woodie Woodie, which was sown in September 2015 and thriving in the cooler Pilbara temperatures. Winter crops First in the Pilbara LEFT: Nat Byrne, Warragine station, commences winter seeding program: The winter trial seeding program is in full swing as Nat Byrne of Warrawagine station seeds a mix of perennial and annual crops. ABOVE: Variety of winter species trialed at Woodie Woodie: Oats, barley, maize, vetch, French serradella, and Persian, arrowleaf and balansa clovers are some of the winter species the department is trialling at the site, using surplus mine dewater to irrigate the crops. THe ReMoTe WooDIe WooDIe research site located in the Pilbara almost 200 kilometres east of Marble Bar has again broken new ground, seeding its winter crop trial program. oats, barley, maize, vetch, French serradella, and Persian, arrowleaf and balansa clovers were planted at the 38 hectare irrigation site the first time barley and these particular legume species have been grown in the region. Led by the Department of Agriculture and Food, the trials are part of the Pilbara Hinterland Agricultural Development Initiative (PHADI) a pioneering project testing the use of surplus mine dewater for irrigated agriculture in the region. Department project manager Chris Schelfhout, who recently visited the site during winter seeding, said the project supported the department s goal to enable businesses to expand irrigated agriculture across the north of Western Australia. The trial s centre pivot irrigator has been sown to a range of temperate grasses and legumes to assess suitable crop rotations of annual species, Mr Schelfhout said. Clovers, serradella and vetch were selected to provide a high-protein fodder option should irrigators choose to run a stand and graze system. The site has progressed significantly since its establishment in 2015, from undeveloped pastoral grazing land to intensified irrigated land. I commend Warrawagine Pastoral Clovers, serradella and vetch were selected to provide a high-protein fodder option should irrigators choose to run a stand and graze system. Company staff for their outstanding efforts in developing the Woodie Woodie trial site and preparing a clean, level seedbed for the research program. Mr Schelfhout said while onsite, he had the opportunity to inspect the trial lucerne crop which was sown in September 2015 and was flourishing under irrigation and cooler weather. Rhodes grass had been observed shutting down in cooler parts of the Pilbara from about May to August. To verify the period of reduced production of Rhodes grass at Woodie Woodie, perennial species remained in the ground to enable staff to monitor their performance over the cooler months. Mr Schelfhout said the project s reliance on dewater from the nearby Woodie Woodie manganese mine posed a risk to the continuity of water supply at the site with the recent fall in commodity prices and subsequent changes to the mine s operations. This situation demonstrated the need for secure access to alternate water sources to ensure uninterrupted irrigation, he said. PHADI is delivered by the department in partnership with the Pilbara Development Commission and the Department of Regional Development, in close collaboration with the mining industry, Aboriginal groups and the pastoral industry. The $12.5 million Initiative is funded by the State Government s Royalties for Regions initiative. Trial operations at Woodie Woodie will conclude later this year, however the PHADI team is working with project partners to investigate options to continue irrigated agriculture at the site beyond the trial program. 8 The Overflow - Winter 2016 The Overflow - Winter

6 agricultural development within La Grange, he said. Many have told us they now know their neighbours much better than before. Two of the three traditional owner groups are now planning to include irrigated agriculture in their pastoral operations, and several other landowners are either expanding or submitting new proposals for development. Mr ham said the project also included market analysis and economic research to provide guidance on development costs and potential new markets and supply chains. The La Grange project is part of the regional economic Development Water opportunities Project led by the Department of agriculture and Food and made possible by royalties for regions. The outcomes of the La Grange project will be used by the Water for Food project. More information on La Grange can be found on the department s website agric.wa.gov.au. The mapping, in particular, will show soil types, depth to water, the locations of new monitoring bores, and wetlands, which are combined to identify prime locations for irrigation. Foundation Laid For Future Irrigation Development in the North Kirrily Palmer, client engagement advisor, DaFWa Our MediaPlus Filtration System Reduces: Iron Manganese, Arsenic Hydrogen Sulfide Uranium, Radium Organics, Odours Heavy Metals & more Four years of research by the Department of agriculture and Food in the La Grange area has laid the foundation for the establishment and growth of new irrigated industries and development in the north. The La Grange agriculture opportunities project, which started in 2012 and concluded on June 30 this year, has identified over 50,000 hectares of sites with shallow groundwater potentially suitable for irrigation development south of broome. The department s La Grange project manager chris ham said the project had provided the foundation to support sustainable agricultural development which would generate business growth and employment opportunities for northern communities. The project has demonstrated that land and water development can work sideby-side with natural resource and cultural management, Indigenous protected areas and the pastoral industry, Mr ham said. at forums in broome and Perth, the most suitable land for development was showcased with possible future scenarios based on the water allocation of 50 gigalitres, and base costs and market potential for future agriculture in the region. The mapping, in particular, will show soil types, depth to water, the locations of new monitoring bores, and wetlands, which are combined to identify prime locations for irrigation. This information has been provided directly to individual landowners in the region to consider, and as a result, several new projects are being developed. Mr ham said the La Grange project had fostered strong relationships between key stakeholders including the traditional landowners from yawuru, Nyangumarta and Karajarri country, pastoralists, horticulturalists and government agencies. stakeholders have collaborated to develop a shared vision for the future of Chemical free!

7 COMMUNITY IRRIGATION PROJECTS EXPANDING UNDER WATERING WA WATERING WA IS A NEW $30 MILLION ROYALTIES FOR REGIONS FUNDED INITIATIVE LAUNCHED LAST MONTH IN KELLERBERRIN BY WATER MINISTER MIA DAVIES AND REGIONAL DEVELOPMENT MINISTER TERRY REDMAN. WaterWA Graph Ministers Redman and Davies visit a government community water supply dam in Kelleberin LEFT TO RIGHT: Minister Davies Watering WA launch, Minister Redman, Kelleberrin townscape. WATERING WA GRANTS support development of water infrastructure at a community level to create new and improved nonpotable water supplies in areas that are vulnerable to water shortages. Watering WA is built on the back of the success of the Department of Water s Community Water Supply Program, which has funded over 100 successful projects in dryland areas of the State in the past 20 years and was featured in the There are three key delivery areas for Watering WA - towns, farms and regional waterways, Minister Davies said at the launch. Under the town component, $21.6 million will be spent on infrastructure in regional communities to harvest, store, treat and distribute stormwater, recycled water and bore water for irrigation and community use. As part of Watering WA, grants available to towns and communities will increase by up to $2 million, from the $100,000 grants currently available. This part of the program will have an initial focus on more than 60 local government areas from the Mid West to dryland, and receive less than 600mm a year average annual rainfall. Department of Water Rural Water Planning Manager Mike Allan said this type of climate created challenges in the provision of water for ovals, townscapes, parks and community needs. This is something we have to work harder to achieve. Watering WA funding provides a catalyst to help achieve this goal, Mike said. When completed, Watering WA funded projects will make hundreds of millions of litres more water available for community and industry use in agricultural towns and communities. The bulk of this program enables the maintain community public open spaces such as sporting grounds and townscapes. By having infrastructure that better captures and stores rainfall and stormwater, there is more water available for communities to use in periods of little or no rainfall, Mike said. Last year 15 projects across eleven shires in the Mid West, Wheatbelt and Great Southern were funded, and another 10 were approved this year and are scheduled for completion. Some projects aim to maximise unused storage facilities such as unused drinking water dams and some improve existing non-potable supplies to ensure purpose water supplies into the future. A strong focus of Watering WA is to reduce the reliance on scheme water supplies treated to drinking water standards, for non-drinking purposes such as turf watering, crop spraying and livestock requirements. This increased water availability reduces the need for use of valuable town scheme This increased water availability reduces the need for use of valuable town scheme water supplies, including use of standpipes for emergency livestock and community use. water supplies, including use of standpipes for emergency livestock and community use, Mike said. The second component of Watering WA s scheme water reduction focus has seen $4.4 million made available for rebates for farmers to boost on-farm water supplies. is available to farmers with access to reticulated scheme water, which is the same water used for drinking purposes, Mike said. It continues to be open to farmers with no access to reticulated scheme. Either way, on farm water shortages result in more pressure on town drinking water supplies, with farmers having to come in and use standpipes for livestock In times of extreme dry, the government subsidises the carting of emergency nonpotable water for livestock to these shires. the focus to improving waterway health with $4 million for important water quality improvement work in the lower Avon catchment. This work helps restore key pools and water bodies, protect riverine vegetation and support these important community assets, as well as improve water quality.

8 Department of Water rainfall and streamflow summary June 2016 The DeparTmenT of WaTer produces monthly summaries of rainfall and streamflow across the South West from June to october and the June 2016 summary is now available online. rainfall occurs mainly from the end of autumn to the start of spring in the south west and the summaries provide a spatial snapshot of rainfall and streamflow from month to month, Dr Sandie McHugh, Branch Manager, Water resource assessment at the Department of Water said. The summaries include: monthly and year to date rainfall and streamflow at measurement stations across the south west in comparison to the average. Rainfall indicators developed representing inflow to the Integrated Water Supply Scheme (IWSS) dams and recharge of Gnangara groundwater levels. Rainfall and streamflow tracking at four sites; Gingin, Harvey, Kalgan and pemberton and potential scenarios for the remainder of the year based on recorded values from Some points to note about the June 2016 summary: Rainfall in June was average to below average across the majority of the south west although some sites on the south rainfall occurs mainly from the end of autumn to the start of spring in the south west and the summaries provide a spatial snapshot of rainfall and streamflow from month to month. coast and Jurien Bay and Salmon Gums recorded higher than average rainfall. January to June rainfall remains above average across the south west because of higher than average rainfall earlier in the year. Four sites have highest on record rainfall for the year to date the wheatbelt towns of Kellerberrin, Narembeen and Newdegate and the south coast site at Pallinup River-Bull Crossing. January to June rainfall typically accounts for 45 per cent of yearly rainfall across the south west Streamflow for June and the year to date is average to above average along the south coast and average to below average from Gingin down past Perth to Capel. Harvey River has recorded the lowest streamflow on record in June and the year to date - only 99 ML was recorded and average streamflow for January to June ( ) is 4,716 ML at the Dingo Road streamflow gauge. January to June streamflow typically accounts for 20 per cent of yearly streamflow across the south west. a lot more rainfall is required to recharge Gnangara groundwater levels to those recorded at the end of last winter a 414mm deficit at the end of June Links to the DAFWA and BoM rainfall forecasts can be accessed from the website. The Department of Water use both outlooks and recommends looking at the confidence in each forecast in combination with the recent conditions. It s too early in the season to make conclusive statements about likely conditions and water supplies at the end of October - seasonal conditions will become clearer by the end of August, Sandie said.

Above: Pinch Drip PC A new pipeline to boost the volume of water available to Carnarvon horticulture growers and expand production in the region commenced at the end of May Construction company SSP Diverse had been awarded the contract to build the 25 kilometre long Northern Borefield Pipeline, as part of the $25 million Gascoyne Food Bowl project, made possible by the State Government s Royalties for Regions program. Project manager Tony Della Bosca said the contract was the culmination of four years of work towards providing a high quality water supply and associated infrastructure to increase irrigated agriculture production in the Gascoyne by 400 hectares. When the pipeline is completed in three months, the current water capacity will increase from 183 to more than 550 litres per second, he said. The pipeline will be supported by the electrification of the northern bore field, which will ensure the consistent and more efficient delivery of water for horticultural crops. More than 120 exploration bores have been drilled by the project, from which 35 production bores have been established to deliver four gigalitres per year with an average flow of more than 12 litres per second per bore. The drilling program was also set to recommence by the end of May to develop an additional 6-8 production bores in order to verify the Northern Borefield s water resource for sustainable delivery and possible further expansion in the future. Mr Della Bosca said the project would complement previous Royalties for Regions investments into Gascoyne Irrigation Pipeline and Flood Mitigation Works to create a viable and sustainable Carnarvon horticulture precinct. This Royalties for Regions project will satisfy growers need for a reliable, effective water supply, providing confidence for industry growth, he said. It will also ensure a sustainable water resource to service potential new irrigated agriculture opportunities. In addition to the drilling and pipeline work being conducted for the Gascoyne Food Bowl project, progress for land development is continuing. Technical studies including an airborne electromagnetic survey (AEM) analysis, soil surveys, revised floodway modelling, land use constraint mapping and flora and fauna surveys have been undertaken to identify suitable parcels of unconstrained land. As a result, about 600 hectares of high to moderate capability land has been identified for potential annual and perennial horticulture. The GFB District Structure Plan and Scheme Amendments, which will incorporate the new GFB land into the Shires town planning scheme, has been adopted by the Shire of Carnarvon and circulated for public consultation. The town planning scheme is part of a parallel process to expand the land in Carnarvon. Department of Lands will continue to work on changing the title of the land from Unallocated or Vacant Crown Land and Pastoral lease tenure into a Section 79 lease (a General Lease granted for a purpose and subject to conditions), and then ultimately to freehold, which requires Native Title negotiations to occur first. The Department of Lands is currently seeking approval from the Minister for Lands to proceed with tenure change and Native Title negotiations. Once the 400 hectares of land is released, horticulture production in the Gascoyne will have the capability of generating an additional $20 million per year.

10 Raking the amendments evenly over the surface Careful placement of the bagged amendments to ensure even application Introducing Andrew Corrigan from C-Wise, and Paul and Linda Mitchener from The Green Life Soil Company Ploughing the amendments into the upper 100mm of the root zone The tines of the plough are precisely set to blend the amendments uniformly into the root zone Best Practice Lawn Preparation and Maintenance Project Soil preparation, seasonal watering, fertilising, and mowing trial By Nick Bell, Advanced Diploma Horticulture-Turf, Lawn Specialist. In my occupation as a lawn and turf consultant, I regularly inspect home lawns and advise owners on how to water wisely in accordance with the regulations, and to manage their lawns in an environmentally responsible co-ordinated way, combining controlled watering, slow feeding with organic nutrients, and recycling grass clippings. Inspired by concerns expressed by Garden Guru, Trevor Cochrane in December last year, and motivated by questions and answers at a meeting of the Garden Industry Reference Group, chaired by Water Corporation, General Manager Assets Planning, Ashley Vincent on March 1st this year. I initiated a conversation with Helen Gigney, Project Officer-Water Efficiency and Ashley about implementing a project aimed at reducing the amount of water, fertiliser, mowing and maintenance needed to maintain a typical home lawn. The Cyril Jackson Senior Campus provided a site adjacent to their ArtsHouse that is representative of a home lawn and teachers, students, and the community will contribute to the project. The Water Corporation have acknowledged the project, and in-kind funding and support has been received from The Turf Growers WA, Irrigation Australia, Elliott s Irrigation, John Forest, the Green Life Soil Company, and Rover Mowers. Introduction With concern about low inflow into dams there has been discussion about changes to the watering restrictions that currently limit scheme water irrigation to 2 applications of 10mm on rostered watering days each week. Seasonal irrigation adjustments are critical to efficiently water turf. The volume of water needed to maintain lawns in September and May is vastly different to what is needed in January and February. With the average lawn size for new homes currently around 65m2 compared with 120m2 a decade ago (WA turf Growers pers: com), it is increasingly more viable for households to invest in soil improvement, sophisticated efficient irrigation practices, slow feeding, and judicious mowing to maintain them. Objectives The objective of the trial is to investigate if the volume of water needed to maintain functional sustainable lawns can be reduced and to share the knowledge with home Photos by Nonie Jekabsons lawn owners. Sites, treatment and experimental design The trial will be conducted at: Cyril Jackson Senior Campus at 53 Reid Street, Bassendean. The trial plot has been amended to increase water holding capacity and moisture content in the upper surface of the root zone by incorporating 15mm Green Life Lawn Dress containing yellow and Gingin red sand, granite dust, zeolite and a blend of slow release nutrients and in the northern section, and 10 mm C-Wise Humicarb compost blended with Bentonite clay and zeolite in the southern section. The materials were ploughed into the upper 100mm (primary root zone) of the in-situ sand of each section. This stage of the project was completed on Sunday 19 June. The area of the lawn is 112 m2 The turf is Soft Leaf Buffalo CV: Sapphire The lawn will be watered, fertilised and mowed in accordance with best practice and accurate records will be kept. Two Hunter PRO-C 8-Station Irrigation Controllers one equipped with a Wireless SOLAR-SYNC Sensor will be installed.

Both controllers shall be set to apply historical monthly percentage requirements: September 4mm twice per week October 6mm twice per week November 8mm twice per week December 10mm twice per week January 10mm twice per week February 10mm twice per week March 8mm twice per week April 7mm twice per week May 6mm twice per week Both controllers will be connected to water meters Sprinklers are Hunter Pro-Spray PRS30 fitted with number 12 fixed arc nozzles with a precipitation rate of 50mm per hour. The application rates have been programmed by Irrigation Waterwise Irrigator, Elliott s Irrigation, with input from John Forrest of Challenger Institute of Technology. Final surface preparation, incorporation of Organic 2000 Starter Fertiliser and the installation of the Sapphire Soft leaf Buffalo Lawn is scheduled for mid-august and will be done by Westland Turf. The new lawn will be irrigated if needed in accordance with the watering exemption for new lawns, and he seasonal watering regime will begin on 1 September. The Project will be launched on Thursday 1 September and at the Cyril Jackson ArtsHouse Garden. CJ Staff and students, Project contributors, Town of Bassendean officials, and Media Representatives will be invited. The lawn will be mowed with a sharp correctly set cylinder Rover Kensington mower at a height of 12mm whenever the vertical height of the grass reaches 18mm and the clippings returned to recycle nutrients and increase the organic content of the soil. The 6-bladed cutting cylinder will be replaced with a verticutter reel to prevent the accumulation of thatch in February Strong healthy turf without excessive growth will be maintained by slow feeding by top dressing with a 3mm thickness of Turf Perfect mature compost in October 2016 and in April Supplementary applications of liquid compost extract will be made for comparison on sections of the lawn at 4-6 week intervals during the period October to February. The quality and appearance of the turf will be assessed visually, and photographed at set photo points and times of day, and data recorded by N. Bell in third week of every month of the irrigation season Project timeline 12 months. Communication This best practice demonstration/soil amendment trial is complementary to the soil amendment turf research project already underway at UWA s Shenton Park Field Station. The emphasis of this work is to teach home lawn owners how to maintain their lawns with less water. Cyril Jackson Senior Campus includes a Teaching workshop Facility, and teachers, students, ArtsHouse Garden Core Committee Members, and the community will contribute to the research. Cyril Jackson Senior Campus is the hub of the community and all participants will contribute to workshops that will be held in spring, summer, autumn and winter to teach and demonstrate Best Practice Water-Wise Lawn Care to the Bassendean Community and neighbouring areas. Progress reports will be circulated quarterly in December 2016, and March, June, and September The Final Report will be completed in October 2017 and distributed to the Horticultural Media Association for circulation to the wide cross section of home gardeners. Articles will be written for publication in the West Australian, Sunday Times and various gardening magazines, and newspapers. Author participation in Radio Talk Back Gardening Shows at the ABC, 6PR and Curtin Radio Let s Talk Gardening. And a possible feature on Channel 9 This Day Tonight. Cyril Jackson Senior Campus Media Department will contribute to the documentation of the project. Progressive stages of the project will be posted regularly through the CJSC ArtsHouse Facebook group and the Cyril Jackson Senior Campus Facebook page. When completed, the video will be available to all in-kind contributors and will acknowledge their contributions to the project.

11 Green... but the Green Space Alliance is helping to make it easier! It s not easy being brown parks are not an option for the future of my Perth. We are advocating for smarter ways to ensure adequate water is available for these vital living green areas. Perth s vibrant Green spaces are crucial to our health and way of life and they are at risk of being lost as they are increasingly being threatened by urbanisation and degradation. The growth of Perth places great pressure on land space and water resources, and as a result the provision of green space has become a major challenge. The Green Space Alliance (GSA), a group of Western Australian amenity horticulture industry groups and aligned organisations, are working together to promote the benefits of green space in all its forms, including parks and recreational reserves, civic spaces, residential gardens and the urban forest more broadly. The GSA believe Perth has reached a critical point in time when action must be taken to protect existing and future green space in all its forms and have recently launched a discussion paper and position statement entitled Improving Urban Liveability. The GSA seeks to advocate to key political and government stakeholders for policy reform which will deliver healthy and resilient communities. The discussion paper, position statement and a video highlighting the importance of green space can be accessed at GSA s ambassador and WA s own gardening guru, Neville Passmore, is urging the State Government to take this seriously. Brown parks are not an option for the future of my Perth. We are advocating for smarter ways to ensure adequate water is available for these vital living green areas. Well designed and properly maintained playing fields, passive recreational areas, urban forests, home gardens, even green walls and roof gardens are needed, not only to combat the retained heat of our cities and suburbs, but to make this place we call home - liveable. Our parks and urban green spaces are more than just a place for your children to play or to walk your dog, they have become the outdoor gym, the weekend local to 20 The Overflow - Winter 2016 The Overflow - Winter

12 catch up with mates, the movie theatre, the concert venue and so much more. They are the lungs of our city and keep us connected with nature. These important attributes must be protected now and for generations beyond that of my grandchildren. There is overwhelming evidence demonstrating the benefits of green space, including improved community health, provision of ecosystems services and increased property values to name a few. With a population of just over two million at present, Perth and the wider metropolitan area is projected to grow to near 3.5 million people over the next 30 years (WAPC, 2015). This population expansion places great pressure on land, space and water resources, and as a result the provision of green space has become a major challenge. A key challenge identified by the GSA is that the economic, social and health benefits generated by green space is not adequately understood or acknowledged. Whilst research has been undertaken in Australia and internationally to measure these benefits, a comprehensive study of the value of space in Perth has not been undertaken. The provision and maintenance of public green space is a costly endeavour, the responsibility for which usually falls to fiscally constrained local governments. Prioritisation and finding efficiencies is crucial. Research that quantifies the value of green space in Perth by placing a monetary value on green infrastructure will illustrate the value of investing in green infrastructure to the public and other stakeholders. Understanding and promoting this information, potentially in co-ordination with the GSA will raise awareness amongst the community but also with developers and local governments. Sue McDougall Horticulturalist and 6PR gardening expert implores that, State Planning policies need to recognise the importance of natural green spaces and existing trees within the urban environment and consider these areas an asset to improve urban liveability. As the population increases future generations should not be denied access to unique natural areas due to short term or not fully considered planning decisions. Our planning and water management policies do not sufficiently support the protection of existing green space, nor the creation of adequate new green space. Thanks to this lack of guidance, the form, location and quality of new public green space is often inappropriate or insufficient. Whilst public open space and provision of green space is addressed in planning policy it is not prioritised, with public open space therefore not considered early enough in the development process to ensure good outcomes. The quality of existing public open space is significantly compromised by water supply and allocation constraints. The wasteful and inefficient use of our scare water resources must be resolved to sustain quality green space into the future. The GSA urge the WA Government and LGAs to urgently develop progressive policies which address water and planning challenges and additionally promote an environment of innovation which supports the development of green space in Perth. Green Space Alliance Principles Green Space Alliance Recommendations 1. Improve liveability by placing greater prominence on green space in the planning process and prioritise the creation of sufficient, quality designed public open space. The Western Australian Planning Commission s current Planning Review for Better Design process should respond to green space concerns by improving planning policy to provide greater protection for existing vegetation, and establish minimum green space needs within new development at lot and precinct scales. 2. Prioritise water resources, improve water management practices and support ongoing research and demonstration of innovative urban they are the lungs of our city and keep us connected with nature. these important attributes must be protected now and for generations beyond that of my grandchildren. water management solutions to sustain quality green space. The Western Australian Government s proposed Water Resources Management Bill should protect potable water resources by developing non-potable water use targets for irrigation to facilitate the uptake of fit-for-purpose water sources to meet green space irrigation requirements. 3. Recognise Perth s unique green space and enhance biodiversity protection and management practices. The Western Australian Government and Local Governments should develop Green Space Strategies which plan for the management of green space and identify green space targets. Management policies, such as bushfire mitigation and roadside vegetation legislation should reflect growing awareness of the value of vegetation and better address linkages to water sensitive urban design. 4. Recognise the value of the health and economic benefits green space generates for WA and ensure appropriate resourcing and funding. In partnership with industry, the Western Australian Government should undertake research that quantifies the value of green space in Perth. Consideration should also be given to allocating sufficient funds towards State and Local Government green space enhancement activities. 5. Promote ground-up engagement and communication across the community, industry and government to increase end-user involvement in urban green space, and support social equity outcomes. The Western Australian Government should undertake transparent consultation with industry and the community to ensure the value of urban green space is embedded in legislation and relevant policy instruments, including prioritising the passage of the Public Health Bill 2014 through Parliament, supported by a Public Health Outcomes Framework, which considers how green space contributes to health and wellbeing. The GSA is aligned with other urban greening initiatives such as Vision. The GSA is currently briefing government agencies and hopes to work with governments of the day to support and assist in developing appropriate policy and programmes to deliver on the GSA principles and recommendations. Liveable communities of the future are dependent on the quality and accessibility of green space. The GSA is calling on all stakeholders and the broader community to get behind this initiative and contribute to making our urban environment greener, healthier and more enjoyable for us to live.

13 Design Shop The Water Corporation and the Irrigation Australia (IAL) have teamed up to develop a program aimed at reducing water consumption outside the home. Water Corporation scheme and guidelines to help create WATERWISE VERGES VERGES FORM IMPORTANT green spaces in our community, by assisting with urban cooling and creating ecological corridors through our streetscapes. If designed, installed and well maintained, waterwise verges contribute many environmental benefits. Many local governments have policies in place to encourage residents to create waterwise verge gardens. However, there are few clear guidelines on what a waterwise verge actually looks like or what is considered to be best practice. To support the creation of waterwise verge gardens across the State, Water Corporation developed a set of best practice guidelines and launched a new incentive scheme to support local government to waterwise verges in communities. To determine best practice guidelines our Waterwise Partner, Josh Byrne and Associates, reviewed existing local government policies on landscape design and management principles. The review established many local governments provided correct information, however, there were some areas for improvement. This included irrigation selection and watering regimes, mulch application, both quality (size and type) and quantity (depth) and the importance of ongoing maintenance (weed removal, irrigation inspection, plant health). Following the review the Waterwise Verge Best Practice Guidelines were developed to assist local governments to provide the right level of information to residents. The aim is for local governments to use the guidelines to develop a verge policy, or Many local governments have policies in place to encourage residents to create waterwise verge gardens. However, there are few clear guidelines on what a waterwise verge actually looks like or what is considered to be best practice. amend existing verge policies to align with guidelines. Key areas from the Waterwise Verge Best Practice Guidelines include: Approvals and controls: Individual council requirements and external documents and controls. Design considerations: Aesthetic, practical water management and safety issues. Preliminary works and soil preparation: Removing existing verges and verge stabilisation. Plant selection: Low water use and local plant species recommended. Mulch: Mulch use and quality (organic/nonorganic, size considerations) addressed. Irrigation and watering: Preference identified for no irrigation, but where employed sub strata drip irrigation is recommended. Maintenance: Recommendations made for regular maintenance and upkeep. In addition to guidelines, we also produced a step by step brochure for residents on how to create a waterwise verge garden, in accordance with their local government requirements. This brochure is available from our website watercorporation.com.au/waterwiseverges. To further support Waterwise Councils to promote waterwise verges in communities, we launched an incentive scheme. Through the scheme, endorsed Waterwise Councils are eligible to receive matched funding to support their own waterwise verge incentive or rebate schemes. We encourage our Waterwise Partners in the irrigation industry to share information about the waterwise verge guidelines and incentive scheme with your clients. For more information about waterwise verges or to join our Waterwise Programs, visit watercorporation.com. au/waterwiseverges or waterwise. programs@watercorporation.com.au With more than 50% of household water being used on the lawn and garden, and an increasing number of Do-It-Yourself enthusiasts installing their own irrigation systems, it is important that the people employed in irrigation design shops have the knowledge and skills to provide their customers with waterwise advice, products and services.
